TriboDyn Tri-EX² 75W-140 is a full synthetic gear oil engineered with patented ceramic coating technology — the first oil to receive a United States Functional Patent in over 30 years. This heavy-duty formulation combines advanced synthetic base stocks with a robust sulfur-phosphorus extreme pressure additive package, friction modifier, and proprietary ceramic coating technology that actively seeks out areas of intense heat and friction to form a self-lubricating ceramic film.
This film not only prevents wear but can help repair minor surface damage, delivering unmatched load-carrying capability and extended component life. Meeting or exceeding API GL-5, API MT-1, MIL-PRF-2105E/D, Mack GO-J, and Mack GO-H specifications, Tri-EX² 75W-140 is ideal for heavy-duty truck differentials, towing applications, and high-torque gearboxes requiring maximum film strength.
With excellent low-temperature performance, thermal stability, anti-foam, anti-rust, and anti-corrosion properties, this gear oil delivers proven performance in the most demanding conditions.
Key Benefits:
- Patented ceramic coating technology that helps repair minor surface damage
- Full synthetic 75W-140 for heavy-duty applications
- Excellent extreme pressure and load-carrying capability
- Broad OEM approvals (API, MIL, Mack)
- Strong cold-flow and thermal stability
- Reduces wear and extends component life under severe conditions
Recommended Applications: Ideal for heavy-duty truck differentials, towing, high-torque gearboxes, and other demanding applications where maximum protection and potential surface repair benefits are required.
